BY 8);" ,fiwalJd kn c ATTORNEYfi Unite Stats This invention relates to anovel terry fabric suitable for towels, garments, bedspreads, draperiesand the like and to a method of making such a fabric.

It is the primary object of this invention to provide a terry fabric andmethod of making the same wherein the fabric has a base with terry loopsprojecting from both faces of the base, the terry loops being formed oftwo or more types of yarns of relatively varying shrinkability which areso arranged that loops formed of at least one of the types of yarnsproject from one face of the base, and loops formed of at least oneother of the types of yarns project from the opposite face of the base,in at least a portion of the fabric, so that opposite faces of thefabric are of different appearance.

It is another object of this invention to provide a novel terry fabricwhich is inexpensive to manufacture and wherein the finished fabricincludes one or more relatively high or long pile design areassurrounded by relatively lower pile areas, and vice versa, on both facesthereof.

It is a more specific object of this invention to provide a novel terryfabric and method of making the same and wherein the fabric has a wovenbase, terry loops carried by and projecting from both faces of the base,and the loops being formed from two or more types of yarns of varyingshrinkability. In certain areas, first loops of at atent least one ofthe types of yarns project from one face of the base opposite from theface of the base from which the loops of at least one of the other typesof yarns project. In other areas the respective aforesaid yarns arearranged in an opposite manner therefrom to project from the other faceof the fabric.

It is still another object of this invention to provide a terry fabricand method of the character described and wherein at least one of theterry pile yarns is a bulk yarn.

According to the present method a terry fabric is woven of two or morepile yarns of different shrinkage characteristics with the differenttypes of yarns appearing in the form of terry loops arranged inpredetermined order on opposite faces of the fabric, and with all theterry loops projecting substantially the same distance from the basefabric at each face thereof. Thereafter, the fabric is treated to causethe yarns to shrink relative to each other or to cause at least one ofthe types of yarns to shrink relative to the other type or types ofyarns so that loops of different length are produced from the differenttypes of yarns of which the fabric was originally woven and on oppositefaces of the fabric.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawings, in which- FIGURE 1 is an elevational view ofone face of a towel, representative of a terry fabric embodying thepresent invention, showing the same as it comes from a loom with areasdefined in broken lines representing loops formed from different typesof yarns;

FIGURE 11 is a view similar to FIGURE 10, but showing the three terrypile yarns of one set in exploded relationship.

Heretofore, in order to produce various aesthetic effects in terryfabrics, such as blocks, stripes or figures of terry loops, commonlyknown as jacquard designs, it has been common practice to form theeffect areas by weaving sections in which all the terry loops wereformed on the opposite face or back of the fabric, thus leavingcomplementary sections of the terry fabric which were devoid of terryloops; or lateral stripes were formed in the fabric by varying theamount of slack produced in the terry warps during weaving to produceterry loops of different heights. In another method, terry fabric waswoven from terry warps which were previously dyed two or more colors, ortwo or more colors and white, and wherein the figure or design wasproduced by forming the loops of one color on one face of the fabric tooutline the design and the loops formed of another color or white werearranged to surround the figure. Of course, the areas of the face whichwere not to include some colors while including another color would havesaid some colors of loops formed on the opposite face of the fabric.

The present fabric includes intricate jacquard designs which can beproduced on a conventional terry loom without varying the extent towhich the terry yarns are slackened during the formation of diiferentterry loops. The fabric may be woven on any type of terry loom equippedwith a pattern device, although it is preferable that such loom beprovided with a jacquard pattern mechanism for controlling the terrypile yarns so that selected loops may project from either face of thebase.

In the terry pile fabric in accordance with this invention, a basefabric is woven from non-shrinkable or low shrink ground warps and weftsconcurrently with which terry loops are formed on both faces of the baseand in which all the loops are of substantially the same length orheight with adjacent warpwise rows of loops being formed from terryyarns of different shrinkability. Adjacent terry pile yarns may includea non-shrinkable yarn and one or more individual relatively shrinkableyarns, or all the terry pile yarns in each set or group may beshrinkable but capable of shrinking varying amounts.

As is well known, terry fabrics are woven by looping terry yarns aroundspaced weft yarns in each instance,

scenes;

then forming one or' more loose picks in which the wefts arespaced fromthe fell"of'th'e fabric being" Woven, then slackening the terry pileyarns relative to the ground warps and drawing the slack out of the pileyarns with a fast pick wherei'n'the respective weft is beat-up with theone or.more wefts castwithitheloose picks to. thus pile"upjthepiletyarns in the form ofloops whose bights' are spaced" fromtheone or more weftsof which ,the loose" pick's'were previously formedand whose legs are anchored in thebase by theiwefts preceding those ofwhich, successive fast: picks are" formed.

As he retofore; stated, the'warpwise rows of loops may be' formed fromsets'of two or more terry pile yarns of different shrh kability. efie'ctareas'may be formed by throwing the loops formed In Weaving the fabric,mottled" of a firstterry pile yarn to one face of the base whilethrowing" loops formed of a second relatively shrinkable terry pile yarnto the other face of the base during the formation of'every otherweftwise row of terry loops. The faces to whichthe loops of the firstand second-yarns are thrown maybe reversed in forming the interveningweftwi se rows to produce a mottled-area when thefabric is'subsequentlysubjected to a shrinking treatment.

Apleasing effect may be produced by causing all the loops formed of afirst yarn to project from one face of the base fabric and causing-allthe loops formed of a second relatively shrinkable terry" pile" yarn toproject from the other face of the base. The latter type of fabric,

when subjected to a shrinking-treatment, is particularly i useful -inmaking bath mats. 1

In other instances, the fabric may be'forrned by throw- 1 ing' the'terry loopsformed of' a first terry pile yarn or yarns to a first faceofthe'fabric while throwing-the loops formed of a second relativelyshrinkable yarn or yarns to' thesecond or other face of the base. Thelatter arrangement may be'confined to a relatively'large area or areasand this procedure is reversed at other adjacent areas. The'fabric isthen subjected to a shrinking treat ment so that thefirs't-me-ntionedareas on the first face In one embodiment of the invention, arelativelylow' shrinkable or non-shrinkable terry pile yarn is used inalternation with a second relatively high shrinkableyarn 1 across thefabric to'produce the above effects. Ina second form of the invention,several different types of pile yarns 'of relatively varyingshrinkability are arranged acrossthe fabric in each of a plurality ofgroups, there being three different yarns used in this instance-s0 that,in selected areas, three different lengths of loops maybe formed in anypredetermined order to provide loop pile areas of predeterminedconfiguration which may be of three dilferent heights on either or bothfaces of the base, the extentofpile length variation in'th'e effectareas being limited only by the number of different types of yarnsofuvarying shrinkability which may be practically combined in each setof terry pileyarns.

Referring more specifically to the drawings, a first embodiment of theinvention is shown in FIGURES 1 throughS and is illustrated in the formof a towel or bath mat, which is representative of many different typesof articles which may be produced according to the present method, suchas towels,'bedspreads, draperies, rugs,; carpets or certain types ofwearing apparel.

FIGURE 1 shows a front face of the article 10 as it comes off of the100m, with design effect areas 11, 12, 13 being defined in dotted linesin FIGURE 1, since they are not normally visible as the fabric comes oifof .the loom. 1

The areas 11, 12, 13 are surrounded by a main efiect or body area 14. 7Areas 11', 12',.13, 14', on theback face of thefabriclll (FIGURE 3).complement the. areas a 4 11-14. As shown in FIGURE 4, all the areas11-14 and '11'14' are formed of'terry 'loops'which project 'substantially the same distance from each of opposite faces of a base,broadly designated at 15. 7

However, the terry loops are formed from two different types'of'terrypile yarns 20, 21 of-relatively varying shrinkability. For example, theterry pile yarn 20 may be formed solely from cotton fibers and the terrypile yarn 21 may be formed from cotton fibers blended with other typesof cellulosic, natural, animal or synthetic thermoplastic fibers orstrands. If desired, both of the terry pile yarns 20,-21-in each set maybe made from blends '-or plied strands of diiferent types of fibers withthe first terry pile yarn 20 being blended with diiferent fibers ordifferent proportions'of' fibers than the second terry pile yarn 21' insuch a manner that the loops formed of the terry pile yarn 21 willshrink to a greater extent than the loops formed of the terry pileyarn29 when the fabric is subjected to a shrinking treatment, 'as shown inFIGURE 5.

The base 15 is of usual construction, to the extent that it is formedof'weft yarns 22 interwoven with ground warps 23, 2 and, as is usual,one or more of'the ground warps 23,24 may be disposed between eachadjacent pair of terry pile yarns 2%, 21. ln'FIGURES 4 andS, the terryfabric is shown in the'form of a so-called three-pick terry However, itis to be distinctly underterry.

By'cornparing FIGURE 5 with FIGURE 2, wherein the fabric It! is shownafter finishing, it will be noted that long loops are formed ofnon-shrinkable or low-shrinkyarns 20in eifcctareas 12, 13, and shortloops are formed of the second higher-shrink yarns 21 in areas 11, 14.At' the" same time, short loops are formed of "yarns 21' in areas 12','13 at the back face off-fabric i0 (FIGURE 3),

and long loops are formed from'the first yarns 20 in areas" The'yarncapable of'the higher shrinkage and which forms the shortest loops, suchas the yarn 21 in FIGURES 4 and 5, is preferably of a typewhich willbulk; i.e., become lofty and soft, relative to the yarn of which thehigher loops are'formed when the fabric is subjectedto Many diiferent'types of yarn the shrinking treatment. will'bulk when subjected to ashrinking treatment, and such typesof yarns are generally formed byblending a normal or low shrink fiber with a relativelyhigh shrink.

fiber so that, during'shrinking or other finishing treatments; thehighshrink fiber is caused to shrink'in length to, in effect, produceloops or bulges'in the low shrink fibers, causingthelow shrink fibers tostand'further apart within the yarn and-increasing the diameter oftheyarn to' a much greater extent than the extent to which the lengththereof is decreased. 7 V

Yarns capable of desirable shrinkageand 'bulkiness may be obtained byblending cotton fibers with high shrink acrylic fibers, such as Orion,Acrilan, Dynel and Verel; by blending cotton fibers withvinylchloride-vinyl acetate fibers such as VinyontHl-I; blending cottonfibers with polyethylene fibers or other polyolefins; and with othercombinations of synthetic'fibers. Where-the relatively high shrink yarnsare made from synthetic fibers'or filaments, the desired shrinkage maybe obtained by steaming 'thefabric from one-half minute to five minutesin boiling water or steam at boiling temperature (212 F.). Acrylicfibers'start to shrink 'at'approximately 180 F. and are completelyshrunk at approximately 212 The polyolefins start shrinking atapproximately l65 F. and

complete shrinkagetis attained. attapproximatelyl2l2 F.,

and the vinyls shrink completely at approximately F. The amount of thesevarious synthetic fibers blended age obtained therefrom may vary from 22percent to 60 percent.

Water shrinking rayon fibers commonly known as latent crimp Water fibersmay also be used for forming the relatively high shrink terry pileyarns, the only treatment normally required in the water shrinkingfibers is that of soaking the product and then drying it under a minimumof tension. Water shrinking fibers include so-called L.C.W. fibersmanufactured by American Viscose Company, and a so-called Narco #1 rayonmanufactured by North American Rayon Company. Nearly all rayonmanufacturers are familiar with the processes of manufacturing watershrinking fibers. Water shrinking fibers may be blended with cottonfibers at a proportion of from 15 percent to 50 percent, and theresultant yarns may shrink from 15 percent to 30 percent.

The shrinkable terry pile yarns may also be of a type capable of beingchemically treated to effect the desired shrinkage in the yarn. One suchfiber which may be blended, in the range of from 15 percent to 30percent, with cotton, is a latent crimp caustic rayon sold under thename L.C.C. by E. I. du Pont de Nemours & Company. Latent crimp causticrayon yarn will shrink from 15 to 30 percent. Many fiber processingcompanies are capable of producing chemically shrinkable fibers and itis within the scope of the present invention to use any type ofcombination of synthetic, natural, cellulosic, pro tein or animal fibersfor producing the different types of yarns of relatively varyingshrinkability.

The shrinkable yarns may also be formed by plying a relatively highshrink strand or strands with a nonshn'nkable or low-shrinkable strandor strands. For eX- ample, a direct spun rayon strand may be plied witha plain rayon strand to effect the desired shrinkage and bulkiness inthe finished fabric. A direct spun rayon strand is produced byattenuating or drafting rayon fibers, and then breaking the fibersduring the spinning of the fibers, and the plain rayon is formed offibers which are cut before the spinning operation.

The various types of shrinkable yarns set forth above are exemplary ofmany different types of yarns which may be used to produce the fabric ofthe present inven tion, since it is well known that yarns of practicallyany desired shrinkage characteristics may be produced by choosing andprocessing strands to obtain various degrees of shrinkage, and severalstrands or fibers of different shrink-age characteristics may becombined to produce various degrees of shrinkage and bulkiness.

Second Form of the Invention A modified form of the fabric is shown inFIGURES 611 after the fabric has been finished; i.e., subjected to ashrinking treatment, and wherein the terry loops are formed of sets ofthree types of yarns of different shrinkability. A first or front faceof the second form of fabric 30 is shown in FIGURE 6, which includes amain terry loop effect area or body on which two basic design areas 32,33 are formed of terry loops of different heights or lengths. Each ofthe basic design areas 32, 33 of the fabric 30' includes a central,medium-length terry pile area 34 surrounded by an inner border effectarea '35 formed of relatively short terry loops, and a narrow outerborder effect area 36 which is devoid of terry loops on the front faceof the fabric 30 (see FIGURES 8 and 9).

In FIGURE 7, the back or second face of the fabric 30 is shown having amain effect area 31 formed of intermingled medium-length andshort-length loops surrounding basic design areas 32, 33' whichcomplement the respective areas 32, 33 on the front face of the fabric30. Each of the basic design areas 32, 33' is formed of efl ect areas34', 35, 36' which complement the respective areas 34, 35, 36 of therespective basic design areas 32, 33. It will be noted that the centraleffect areas 34' and the inside border areas 35 are defined in brokenlines in 6 FIGURE 7 for the purpose of illustrating the fact that, Whilethese areas 34', 35 differ in appearance and also difier with respect tothe appearance of the outer marginal areas 33', such differences are notentirely clear, especially when all the terry pile yarns are of the sameshade or color, since all of these areas include relatively long loops,but which loops appear to vary as to density because of the fact thatthe long loops are interspersed with short loops in the areas 34', thelong loops are interspersed with medium-length loops in the inner borderareas 35', and the long loops are interspersed with loops of both mediumand short lengths in the outer border areas 36. This is more clearlyillustrated in FIGURE 8, wherein it will be observed that on the back ofthe fabric the outer suffaces of the short loops are represented byrespective dotand-dash lines L, the outer surfaces of the medium-lengthloops are represented by dot-and-dash lines M. Since FIGURES 8 and '9represent the various loop heights in block form, the base fabric 37 isshown in the form of a thin strip in FIGURES 8 and 9.

In order to clearly understand how the various design and effect areasare produced on the fabric shown in FIGURES 6 and 7, FIGURES '10 and 11each illustrates one of the sets of different types of relativelyshrinkable terry pile yarns, following the shrinking treatment, andwherein the non-shrinkable or relatively low shrink terry pile yarn isindicated at '40, the medium shrink terry pile yarn is indicated at '41and the high shrink terry pile yarn is indicated at 42. These terry pileyarns 40, 41, 42

are interwoven with the base 37, which base comprises wefts 43 andground warps 44, 45. With the exception of the different shrinkagecharacteristics of the terry pile yarns 40, 41, 42, the fabric 34) maybe constructed generally in the same manner as the fabric 10, and allthe terry loops may project substantially the same distance fromopposite faces of the base 37 while the fabric is being woven. AlthoughFIGURES 10 and 11 show a single set of three terry pile yarns, it isapparent that such sets may be repeated throughout all or a substantialportion of the width of the fabric 30.

Referring to the righthand portions of FIGURES 10 and 11, it will beobserved that, during the weaving of the complementary main effect areas31, 31', the loops formed from the terry pile yarns 41, 42 are caused toproject from the back face of the fabric and the loops formed of theterry pile yarns 40 are projected above the front face of the fabric. Informing the outer border areas 36, 36', the loops formed of all three ofthe terry pile yarns 40, 41, 42 are caused to project from the back faceonly of the fabric, so the base is visible in the outer border area 36.

In forming the complementary inner border areas 35, 35, loops formed ofterry pile yarns 42 are projected from the front face of the fabricwhile loops formed of the terry pile yarns 40, 41 are projected from theback face of the fabric. In forming the complementary central effectareas 34, 34', the loops formed from the terry pile yarns 40, 42 areprojected from the back face of the fabric while the loops formed fromthe terry pile yarns 41 are projected from the front face of the fabric.

Thus, after the fabric is treated to at least cause the terry pile yarns41 and 42 to shrink relative to each other and relative to thenon-shrinkable or low shrink pile yarns 40, relatively long loops ofterry pile yarns 40 project from the front face of the fabric 30' inarea 31 while short and medium-length loops formed of the terry pileyarns 42, 41 project from the back face of the fabric in area 31'. Loopsof all three lengths formed of yarns 40, '41, 42 project from the backface only of the fabric in area 36; relatively long and medium-lengthloops pro ject from the back face of the fabric in area 35' whilerelatively short loops project from the front face of a fabric in area35. Also, relatively long and short loops, formed from the respectiveterry pile yarns 40, 42, project from I the back face "of thetfabric 30at thearea 34 while-me 31,-34",- 35. The loops in areas 31,34, '35appear to be more dense than the loops in the respective areas 31', 34',

3'5-"jdue to thetfact that loops of two different-lengths areintermingled in-eaoh of theareas' 31 34', 35 and loops'of'only one ofany ofthe threelengths are present in each'of the areas 31, 34,35.

Asheretofore stated, the individual yarns 49, 4d, 42' inreach set may beof any desired construction to effect the desired relative shrinkagethereof during the shrinking shrinkable yarns 40 may be made solely fromcotton fibers, themediurn-shrink yarn 41 may be made from a blend of 84percent cotton and 16 percent acrylic fibers and the high shrink yarn 42may be made from a blend of-low shrink Orion-and high shrinkOi-ion.

It is thus seenthat I have-provided a novel terry fabric and method ofmaking the-same wherein all the terry loopsmay be formed of the sameheight during the weaving of the fabric and, by subjectingthe fabric toa shrinlo ing treatment, embossed-and/or recessed effect areas ofany'desired configuration which project varying dis'-- tances: from the faceof the fabric may be formed.
